4. Open the Windows 7 Control panel, in the search field there, type ” device ” to find the device manager, open it.

5. Find your unrecognized device in the list, right-click on it and choose “update driver software”, “browse my computer for software” and browse to your folder where you unzipped the files. Click next, ignore the warning and the driver installs.

Jeebus Christ. Finally made it work after almost an hour. I would have refrained from posting (Necro), but I had the very same problem today. Thanks a lot! And it’s really funny to see how many people have the same exact problem, almost at the same exact moment now (June 10th) with a webcam they like that’s 10+ years old.

Hi, got this working on windows 8.1 64 bit; it didnt work for me initially but after trial and errror sorted. Followed kapyxxx advice and installed drivers for the SPC900 on Win 7, then updated and resaved the files. Then I went to the unknown device after plugging cam in. Update driver, manually browse but then rather then finding a location I selected let me choose from a list, then video audio controllers but not the one at the top of the list, there was another at the base. I then choose the second Philips with some letters (I cant recall) after, then SPC900 and it worked! Only been on it for hours trying to work out. I have flashed the camera as its a PCVC840K/20 (google and theres a little app to allow that). All for astro web cam.
